Puk (biceps) hasn't yet thrown off a mound, Shayna Rubin of The San Jose Mercury News reports.
Puk started throwing from 90 feet recently, but he still doesn't have a timetable for his return since he hasn't gotten back on the mound. Manager Bob Melvin said Saturday that the team should have a better idea of Puk's return timetable once he throws a bullpen session. The left-hander has been sidelined since April 7 due to a left biceps strain.
